PLUG.

Specification of Letters Patent.

Patented Sept. 30, 1919.

Application filed May 26, 1919. Serial No. 299.861.

To all whom it may concern:

Be it known that I, ELZY O. KUNKEL, a citizen of the United States, residing at Midian, Towanda township, in the county of Butler and State of Kansas, have invented certain new and useful Improvements in Plugs, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain improvemen-ts in plugs and has relation more particularly to a device of this general character especially designed and adapted for use in connection with oil wells or the like, and it is an object of the invention to provide a novel and improved plug of this general character which, when applied, serves to shut off water which may be coming into the bottom of the hole or well.

It is also an object of the invention to provide a novel and improved plug of this general character including an expansible member which operates to maintain the plug in applied position.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved plug whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein:

Figure 1 is a view, partly in longitudinal section and partly in elevation, illustrating a plug constructed in accordance with an embodiment of my invention with the parts in assembled relation.

Fig. 2 is a view in perspective of the elongated member as herein embodied, and

Fig. 3 is a view in perspective of the disk herein included.

As herein disclosed, in improved plug comprises a disk 1, pre erably of metal,

'and which is first properly positioned within the hole or well to be plugged. 2 denotes an elongated solid cylindrical member, preferably of wood, which is positioned directly upon the inserted plug.

An elongated tube T, and preferably of a length not less than five feet, is inserted manner, said tube T will be caused to expand and thereby tightly fit within the hole or well, whereby the desired stopping or plugging is obtained.

The member 2 serves to prevent the mandrel M from being driven through the tube T and striking the bottom of the hole or well while the disk 1 operates to assure the initial positioning of the device.

The disk 1 and the member 2 each have their peripheries provided with the grooves or notches 4 to facilitate the insertion thereof within the hole or bore and particularly the passage thereof through water or other liquid within such hole or bore.

From the foregoing description, it is thought to be obvious that a plug constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein 'drel insertible within the tubular member.

2. A plug of the class described consisting of a disk, an elongated body adapted to be imposed upon the disk, an elongated tubular member adapted to be imposed upon the body, said tubular member being of soft lead and having a tapered bore, and a mandrel insertible withinthe tubular member, said mandrel being tapered.

3. A plug of the class described consisting of a dlsk, an elongated body adapted to be imposed upon the disk, an elongated tubular member adapted to be imposed upon the body, said tubular member being expansible and having a tapered bore, and a mandrel insertible Within the tubular member.

'4. A plug of the class described consisting of a disk, a body adapted to be imposed upon the disk, an elongated member adapted to be imposed upon the body, said member being laterally expansible, and means for expanding the member.

5. A plug of the class described consisting of a dlsk, an elongated body adapted to be imposed upon the disk, an elongated tubular member adapted to be imposed upon the body, said tubular member being of soft lead and having a ta ered bore, and a mandrel insertible within the tubular member, the peripheries of the disk and elongated 'body being provided with re- CBSSBS.
